now do you know if the team is a good defense? you want to know if your team is a good defense, they tackle. >> bernie davis was saying he didn't catch the game against seattle. he noticed the, quote, explosive route, unquote, that opposing defenses were dropping a corner and providing a little help over the top, taking the routes away. do you see that and as a coach or maybe you talked to roman, does it become a game of chess? are you forced to counter that to get him involved in the offense? >> well, there is no doubt about it that teams are taking some measures to control vernon davis, to limit the damage he can do. that is their prerogative. he is always going to be involved because he may not catch a pass in a game like he did this past week. he had one of his best games blocked so well in the past. he was blocking a 350-pound man. and that really helped our offense move the football on the ground because with vernon blocking the defensive end it allowed us to block the remaining interior linemen and get up on the backers. ve
